IMPROVEMENT IN'COMBUSTION-CHAMBERS FOR BURNING HYDROCARBON VAPOR.

Specification forming part of Letters Patent N 0. 137,132, dated March 25, 1873.

To all whom it may concern.-

Be it known that I, CHARLES J. EAMES, of New York, in the'county of New York, in the State of New York, have invented a new and Improved Combustion-Chamber for Burning Hydrocarbon Vapors; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The nature of my invention consists in the construction of a combustion chamber for burning hydrocarbon vapors by providing an outer chamber in which the atmosphere commingles with the hydrocarbon vapor, .and passes thence to an inner chamber, which has a series of compartments through which the atmosphere and vapor pass, further commingling until they pass into the furnace, where they are to be consumed, as will more fully hereinafter appear.

To enable others skilled in the art to make and use my invention, I will now more specifically describe its construction and operation.

In the drawing, Figure 1 is a vertical section, viewing from the front, and Fig. 2 is a longitudinal vertical section of my invention.

A forms the outer walls of my combustionchamber, and is constructed so as to have one of its ends, A, abut against the furnace X, part of whose walls are indicated at 00 m in Fig. 2. B is the air-tube communicating with the outer chamber 0, the air being properly forced through said tube, and controlled by a damper. D is the pipe which admits the hydrocarbon vapors into the chamber 0, and is provided with a valve. E forms the walls of the inner chamber F, (see Fig. 2,) and is firm ly built within the chamber 0, and suitably supported above the walls A. a are openings, by which chamber F has communication with chamber 0 and furnace X. Chamber F is divided into a series of compartments, 1, 2, 3, 4, and 5, by means of partition-walls G, which walls have openings b through them so as to enable the vapor to pass unobstructedly from one compartment to the other. The openings b are so placed as to cause the vapor and air to pass the whole length of each compartment,

and thus causing a more thorough intermixture of the vapor and air. The number of compartments may vary, and to do so it is obvious that it is only necessary to vary the number of walls G.

If the construction above set forth is con formed to the atmosphere will, when it is de sired to o' erate my invention, flow from air tube B into and fill the outer chamber 0, passing onto the front end of the inner chamber F, and there commingling with the stream of hydrocarbon vapor flowing from pipe D. The atmosphere and vapor thus commingled will then flow through openings a. into compartment 1; thence through the opening I) in the several partition-walls G, through the several compartments 2, 3, 4, and 5, into the furnace X.

- When my invention is specially adapted to a puddling-furnace I place the openings at in the rear wall A of the chamber, nearly at the bottom of the chamber F, and the wall A is inclined forward at an angle of about forty five degrees. When the invention is adapted to a reheating-furnace the openings at are placed near the top of chamber F, and the wall A is inclined backward at an angle of about forty-five degrees. When my invention is employed to assist in the reduction of iron ore in a cupola-furnace the openings a in the wall A should be in the position shown in Fig. 2.

Of course I do not confine myself to the cylindrical form of the chamber, as illustrated in the drawing; it may be of any convenient form.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Mixing-chamber,-composed of a series of communicating chambers, or a single mixingchamber divided by perforated walls, in combination with a surrounding air-chamber provided with means for the admission of combustible gases, substantially as specified.

- CHARLES J. EAMES.
